OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

- Class: Square Create a class called "Square", which is inherited from“TwoDimensionShape” class. The "Square" class is used to calculate theArea and the Perimeter of square shapes when their side-length is given, or in contrast,finding the side-length of the square when the Area or the Perimeter of the square is given.The specifications of this class are below. Data Members (Attributes): All are private. sideLength: the sidelight (L) of the square. Methods/Operations/Getters/Setters: Default Constructor: when creating an object this constructor must set the side-length of the square by calling the method setSideLength(). Also, this constructor willcall the findArea() and the findPerimeter() in addition to summaryPrint() to calculateand print all needed information. User-Defined Constructor: when creating an object this constructor shouldfind the side-length of the square by calling the method findSquareSideLength()and pass the Area or the…Implement the following class MyPhoneBook. You can add additional private member variables and functions. The class has the following private member variables: 1- names and phones: Dynamic arrays of strings. 2- phoneBookSize: An int that holds size of phonebook. The Class has the following public/private member functions: 1- Parametrized Constructor that takes the size of PhoneBook and allocate dynamic arrays of names and phones and a copy constructor to initialize a PhoneBook using another PhoneBook. 2- A public function addEntry that adds a name and phone number at the first empty space at corresponding arrays, and returns true if entry is added, false otherwise. An entry is added if there’s space in the array and if phone number if valid. It checks for the validity of the phone number by ensuring that it has 11 digits, and doesn’t include any alphabets or special characters. 3- A public function displayEntryAtIndex(int) that displays a name and phone number at the specified index.…class Point with instance variables as: xCoordinate(int) and yCoordinate(int).

- Write a class that represents a player in a game. The player should have a name, password,experience points, an inventory array of four strings, and a location x,y. Your class shouldhave mutator and accessor methods for all variables. For example: setName(), getName(). Itshould have a suitable display method. Mutators and accessors should be public but allvariables should be private. To implement get inventory, use string * getInv(); Use the scoperesolution operator to implement larger methods such as display(). Use in class methods forshorter methods such as setName(), getName(). (in C++)Example:void setName(string name){this->name = name;}string *getInv();...string* player::getInv(){return inventory;}Note that in the above method setName “this->” is required for disambiguation. If writtenvoid setName(string n){name = n;}“this->” is not required.Write a test program that creates three players and displays them.Example Output:This program generates three player objects and…_ } //**************************************************** // getLength returns the value in the length member. * //**************************************************** double Rectangle::getLength() const { _ _ _ _ _ _ _ _ _ _ } //****************************************************** // getArea returns the product of width times length. * //****************************************************** double Rectangle::getArea() const { __ _ _ _ _ _ _ _ _ _ _ _ } //***************************************************** // Function main * //***************************************************** int main() { double number; // to hold a number double totalArea; // the total area Rectangle *kitchen; // to point to kitchen dimemtions Rectangle *bedroom; // to point to bedroom dimensions Rectangle * den; // to point to den dimentions // Dynamically allocate the objects. kitchen = _ _ _ _ _ _ _ _; bedroom = _ _ _ _ _ _ _ _; den = _ _ _ _ _ _ _ _ _;…build a student class implement the student class with the following instance variables: * id * firstName *lastName *dateOfBirth * Major create an __init__ function adn initialize all the fields make the "major" an option field and set a default value to "undefined" create a setter and getter function for all these five variables create another function: "print_student_info()" which prints 5 pieces of information: id, first name, last name, date of birth, and major. Make sure to have proper formatting done for printing these 5 things. Use the student class Task 1: create an empty list named "all_students" Task 2: create a variable named "id" and initialize it to 100 (some default value to start with, next id would be 101) Task 3: ask the user for input "How many students:" Task 4: Now run a for loop based on that input number and do the following things for each iteration: - get input of student's first name, last name, date of birth, and major - user should be able to skip the…
- Colorful bubbles In this problem, you will use the Bubble class to make images of colorful bubbles. You will use your knowledge of classes and objects to make an instance of the Bubble class (aka instantiate a Bubble), set its member variables, and use its member functions to draw a Bubble into an image. Every Bubble object has the following member variables: X coordinate Y coordinate Size (i.e. its radius) Color Complete main.cc Your task is to complete main.cc to build and draw Bubble objects based on user input. main.cc already does the work to draw the Bubble as an image saved in bubble.bmp. You should follow these steps: First, you will need to create a Bubble object from the Bubble class. Next, you must prompt the user to provide the following: an int for the X coordinate, an int for the Y coordinate, an int for the Bubble's size, and a std::string for the Bubble's color. Next, you must use the user's input to set the new Bubble object's x and y coordinates, the size, and the…USING C++ Implement the Rectangle class below: *******RECTANGLE CLASS******* class Rectangle { private: double width; double length; public: void setWidth(double); void setLength(double); double getWidth() const; double getLength() const; double getArea() const; }; *******END OF RECTANGLE CLASS******* Enhance the Rectangle class with two new member functions: double getPerimeter() - returns the perimeter of the rectangle, i.e. 2*width+2*length bool isSquare() - returns true if the rectangle is a square, i.e. length is equal to width, returns false if not Demonstrate your class works with the main function that instantiates a Rectangle object and shows sample output for these functions workingImplement the following class MyPhoneBook.

- 1. Create a Student class that implements the Person interface. As well as storing the students name and email, also store their course grade (e.g A, B, C) in a member variable. The grade should be accessible via a getGrade method. For the implementation of getDescription return a message along the lines of “A C grade student”, substituting the students actual grade.2. Create a Lecturer class that implements the Person interface. This class should also store the subject that the lecturer teaches. Add a getSubject method, and implement getDescription so that it returns a suitable message, e.g. “Teaches Biology”.3. Create a third class, Employee that implements the interface. This should also store the name of the department the Employee works in (available via getDepartment). Again, getDescription should return a suitable message.Implement a class Clock whose get_hours and get_minutes member functions return the current time at your location. To get the current time, use the following code, which requires that you include the <ctime> header: time_t current_time = time(0);tm* local_time = localtime(¤t_time);int hours = local_time->tm_hour;int minutes = local_time->tm_min; Also provide a get_time member function that returns a string with the hours and minutes by calling the get_hours and get_minutes functions. Provide a derived class WorldClock whose constructor accepts a time offset. For example, if you live in California, a new WorldClock(3) should show the time in New York, three time zones ahead. Which member functions did you override? (You should not override get_time.).c++dayType Class We will be working on a project that designs a class calendarType, so that a client program can use this class to print a calendar for any month starting Jan 1. 1900. An example of the calendar for September 2019 is: September 2019 Sun Mon Tue Wed Thu Fri Sat 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 We will develop several classes which will work together to create a calendar. The first of these classes is called dayType which will manipulate a day of the week. The class dayType will store a day, such as Sun for Sunday. The class should be able to perform the following operations on an object of type dayType: a. Set the day. b. Print the day. c. Return the day. d. Return the next day. e.…
